Abstract Based on nonlinear software, the response of six-fioor frame structure to blasting induced ground motions was calculated.Based on experimental and simulated data, double- parameter damage model of frame structure was introduced; according to “Safety regulations for blasting”, multi-parameter damage criteria was established, and quantitative damage of structure caused by blasting ground vibration was presented.The maximum damage is located at the bottom of the frame structure under blasting induced ground motions, and cumulation damage occupies less part; while the maximum damage is located at the 4 or 5 floor under seismic wave,and cumulation damage occupies the most part. efficient path to assess the damage of frame structure to blasting induced ground motions is submitted.
